Building Hierarchical Martensite [PDF]

open access: yesAdvanced Functional Materials, 2020
AbstractMartensitic materials show a complex, hierarchical microstructure containing structural domains separated by various types of twin boundaries. Several concepts exist to describe this microstructure on each length scale, however, there is no comprehensive approach bridging the whole range from the nano‐ up to the macroscopic scale.

Hydrogen Diffusion and Its Effect on Hydrogen Embrittlement in DP Steels With Different Martensite Content

open access: yesFrontiers in Materials, 2020
The hydrogen diffusion behavior and hydrogen embrittlement susceptibility of dual phase (DP) steels with different martensite content were investigated using the slow strain-rate tensile test and hydrogen permeation measurement.

Martensite’s Logistic Paradigm [PDF]

open access: yesMaterials Research, 2021
Abstract This work introduces a deterministic approach to the martensite transformation curve. Martensite is a nucleation-controlled transformation that has two characteristics: autocatalysis and auto-accommodation. Only a small number of martensite units initially form owing to primary nucleation.

Microstructural Path Analysis of Martensite Dimensions in FeNiC and FeC Alloys [PDF]

open access: yesMaterials Research, 2015
The properties of steels that undergo martensite transformation after or during processing depend on characteristics and arrangement of martensite units within the microstructure.

Lattice deformations at martensite-martensite interfaces in Ni-Al [PDF]

open access: yesLe Journal de Physique IV, 2001
The atomic configurations at macrotwin interfaces between microtwinned martensite plates in $Ni_{65}Al_{35}$ material are investigated using high resolution transmission electron microscopy (HRTEM). The observed structures are interpreted in view of possible formation mechanisms of these interfaces.

Structure and Phase Transition of Fe-Mn Alloy Powders Prepared by Gas Atomization [PDF]

open access: yesMaterials Research, 2015
In this paper we investigated the microstructure and phase transition of atomized Fe-(1.3, 7.9, 11.7 wt.%) Mn alloy powders. The results show that the main phases of Fe-1.3Mn, Fe-7.9Mn and Fe-11.7Mn powders are ferrite, α’-martensite+austenite, α ...

Hybrid Heat Treatment for Conventionally Treatable Steel Powder Reinforced Age Hardenable Aluminium Alloy Matrix Composites and Mechanical Property Evaluation

open access: yesMaterials Research, 2022
The present work is associated with research concentrating on the innovation and use of hybrid heat treatment for eutectoid steel powder (0.8 wt%) reinforced Al-Zn-Mg (Al 7075) alloy composites. Due to high hardness, wear resistance, tensile strength and

The Features of Martensitic Transformation in 12% Chromium Ferritic–Martensitic Steels [PDF]

open access: yesMaterials, 2021
An anomaly in martensitic transformation (the effect of martensitic two-peak splitting in the temperature-dependent thermal expansion coefficient) in complex alloyed 12% chromium steels Fe-12%Cr-Ni-Mo-W-Nb-V-B (ChS-139), Fe-12%Cr-Mo-W-Si-Nb-V (EP-823) and Fe-12%Cr-2%W-V-Ta-B (EK-181) was investigated in this study.
